Conan O'Brien's main guest last night was Beatle Ringo Starr, and he totally geeked out during the interview. Watch those down below. It reminds me of when Conan was first starting and he was so awkward around his guests.But that's not all: Conan joined Ringo's band for a cover of Buck Owens' "Act Naturally" that features Conan smiling so hard his head might fall off. My favorite part? The fact that Conan is like four feet taller than Ringo. Just the best imagery here
